PORTABLE BATTERY LAMP Filed June l5, 1952 Patented Dec. 6, 1932' vUNITED STATES PATENT OFFICE fAUGUsT MITCHELL, OE NEW YORK, N. Y., AssIGNOR `To THE CHAsECOMrANIEs, INCORPORATED, OE WATEREURY, CONNECTICUT, A CORPORATION PORTABLE BATTERY LAMP Application led J'une l' 13,

Y My invention relates to an improved portable battery lamp, the Object being to produce a simple, cheap, compact, attractive and convenient lamp of the character described. Y Vith these ends in view, my invention consists in a portable battery lamp having certain details of construction as will be hereinafter described and pointed out in the claims.

Fig. 2 is a side view thereof; Y

Fig. 3 is an enlarged view showing its twopart case as open;

Fig. 5 is a view in longitudinal section on the line 5-5 of Fig. 1; Y

Fig. 6 is a view in longitudinal section on the line 6-6 of Fig. 1; j

Fig. 7 isa detached view of the bail; and Fig. 8 is a'detail sectional view on the line 8-8 of Fig. 2, showing the locking of the` 'latch by riding the bail over it to prevent the `oase from accidentally Opening.

In carrying out my invention as hereinshown, I employ a struck-up sheet-metal case comprising complementary shells 10 and-11, oblong in form, having square ends and uniting to form a two-part case substantially oval in cross-section. The said shell 10 is formed with integral pintle-sockets 12 and 13 respectively aligned withk corresponding pintlesockets 14 andV 15 formed upon the shell 11 aforesaid. These pintle-sockets lreceive tlie inwardly-turned pintle-ends 16 of a bail 17 substantially rectangular in form and adapted to embrace the case when the same is closed 40 and latched. As shown, theV hinge also comprises a supplemental pintle 18 introduced into the sockets 12 and 15 beforementioned and held against displacement therein by the pintle-ends 16. f

- Opposite the pintle-sockets described, the

11 and the crystal firmly Vheld in place. The said reflector26 is formed at its ends with assembling-arms 28 bent at a right angle 1932. Seria1 No. 616,811.

Vtary ear 19 whenthe latch is snapped over it vto draw the two shellstogether. The Vprojecting outer portions of the rolled ears are Y at such time' lexposed and form between them J 25 which rests upon the inner face of the 65 flange of the bezel, as shown in Fig. 4. 8

Within such a two-part case as described,

I locate a reflector-battery-and-lamp unit,

the several members whereof are constructed and assembled to be normally handled as one piece. The central or key feature of this unit Y VConsists of an Oblongreflector 26, the edge of which is allgd to V,restupon the inner face of the .crystal 25 aforesaid, thesaid. flange `snapping under locking-ribs 27 formed at op- 75 posite points, as shown in Fig. 4, on the outstanding portions of the bezel, whereby theV reector, and hence the unit, of which it is a part, is removably secured to the case-shell to its plane and respectively secured-by eyelets 29 to lthe outer faces of complementary insulating frame-plates 30, which are se- 85 t cured together in proper spaced relation by f means of a bridge 31 interposed between them and secured to them` respectively by the eyelets 29. Midway ofits length this bridge 31 is widened and formed with a circular clearance-opening 33 through which passes-the screw-threaded lamp-receptacle 34 which is mounted in the bottom of the Oblongreector 26. Each of the assembling-arms 28aforesaid is provided withk a'pai'r of lingers 35 v95 entering notches 36in the frame-plates 30 for preventing the rocking of the reflector upon the eyelets 29 with respect to the said plates.

The twobattery-cells`37 and 38 are normally held vin place on opposite sides ofthereflector 26 and against curved seats 39 in the opposite edges of the frame-plates 30 by the tension of three spring contact-plates 40, 4l and 42 secured by eyelets 43 to the outer faces of the frame-plates 30. The double contact-plate is provided with two spring contact-arms 44 which form seats for the corresponding ends of the respective battery cells 37 and 38.

The contact-plate 4l` is provided with a flector against'the edge-of the inner face of the crystal 25. Y

Y -The said contact-plate 42 is provided with a spring contact-armV which forms ya seat for one endk of the battery-cell 38, the opposite endof which is engaged undertension with one of the spring contact-arms 44 of the double contact-plate 40.` yThe said contactplate 42 is also provided with a spring contact-finger 51 positioned to be V'engaged with A and disengaged from a sliding contact-linger located within the shell 1l of the case and .held in place by anV operating-button 52 located upon the outside of the shell and operating through a slot 53 therein.

Vhen the cells are sprung between the respective springcontact-arms of the contactplates, the tension thus'developed is sufficient'V to hold them in place during the handlingof the reflector-battery-and-lamp unit, which comprises the lamp, its reflector, the two insulatingframe-pieces, the two cells and the several contact-plates, all of these parts being assembled so as to be handledv as 'one piece, which is a matter of much convenience in removing and cleaning the crystal and for the replacement of the cells and lamp as need be.

My improved lamp may be Veither carried in the hand by means of its bail, or suspended thereby from any convenient object, or it may be supported thereby upon a table or other corresponding Vsurface lby imply swinging the bail at the required angle with respect to the plane of the lamp.

I claim: l

1. Ina portablebattery lamp, the combination withy a two-part hinged shell, of aremovable reiector-batt-ery-and-lamp unit, comprising a reflector, av lamp located therein, a pair of cells located on opposite sides of the reflector, insulating frame-plates attached to Vthe reflector, and spring contactplates carried by the said frame-plates and having spring contact-arms between which the cells are interposed.

2. ln a portable battery lamp, the combination with a two-part hinged case, of a removable unit adapted to be inserted into and removed from the said case as one piece and comprising a reflector provided at its ends with assembling-arms standing` atl a right angle to it, frame-plates of insulating mate-A rial secured tothe said arms, a bridge interposedbetween the said frame-plates and secured thereto, a lamp located in the reflector and passing through the said bridge, contact-plates secured to the respective frameplates and having spring-arms, and a pair of batterycells interposed between the said arms and held in'pos'ition thereby;

3. In a portable battery lamp, theV combination with a two-part hinged case, of a removable unit adapted to be inserted into and removed from the case as a un'itj and comprising a reflector, a lamp located therein', insulating-plates secured to the reflector, contact-plates carried by the said insulatingplates and having spring `contact-arms, a pair of battery-cells interposed between the said contact-arms, one of the said contact-plates having a spring contact-arm engaging with the button-end of the lamp and provided with a buffer engaged by one of the casepartsl :for keeping the arm in contact with theV button-end of' the lamp and preventing short-circuiting and assisting in holding the unit in place in the case.

4. In a portable battery lamp, the combination with a case having two complementary struck-up shells, the corresponding edges of which are provided with pintle-sockets, of

a bail embracing the case when the shells are closed together'and having its ends turned inwardly to enter the said sockets and form pintles for the hinge-connection of the tWo shells.

5. VIn a portable battery lamp, the combination with a case having two complementary shells having pintle-socketsl upon their corresponding edges, a bail,'the inwardlyturned ends of which enter the said pintlefils sockets and which is adapted to embrace the case when it is closed, and a latch carried bythe opposite edge of one of the shells, and means forA engaging the outer reach of the Too A'im

bail with the said latch for lockingthe same in its closed position.

6. In a portable .battery lamp, the combi- 'nation with a case comprising two complementary shells having aligned pintle-sockets upon their corresponding edges, a bail, the ends of which are turned inwardly to form pintles entering the pintle-sockets ofthe said shells, locking-ears formed upon thevofppo- `site edges of the shells, a latch pivotally mounted in one of the said ears and centrally cut awa'yto fit over the other ear, the portions of the said ears projecting through the latch and receiving between them a portion of the bail after the latch is in position, whereby the bail in its closed position locks the latch in its closed position.-

In testimony whereof, I havev signed this specication. N Y A AUGUST MITCHELL.
